Resumen
The reactions of [Fe3(CO)12] with the bidentate phosphines 1,2-bis(diphenylphosphino)ethane (dppe), 1,4-bis(diphenylphosphino)butane (dppb), 1,1′-bis(diphenylphosphino)ferrocene (dppf) and 1,4-bis(diphenylphosphino)benzene (dppbz) using trimethylamine N-oxide as decarbonylating agent produce the chelated [Fe3(CO)8(μ-CO)2(μ,η2-diphosphine)] and the new series of symmetrical [{Fe3(CO)9(μ,-CO)2}2(μ,η2-diphosphine)] and unsymmetrical [Fe3(CO)9(μ-CO)2](μ,η2-diphosphine)[Fe(CO)4] bridged complexes, in reasonable yield. The complexes were characterized by IR, 31P and 13C NMR spectroscopy, and elemental analysis. Electrochemical studies on these compounds reveal that the substitution of one or more phosphine ligands for carbon monoxide of [Fe3(CO)12] results in a more cathodic potential for the first reduction peak, but is insensitive to the σ-donor capabilities of the ligands. 525 1-2 31 37 Bruce, M.I., (1987) Coord.
